Reset your computer firewall.
Try a different application. (eg. qbittorrent)
Did you recently make any changes to your router?
Are you using VPN or proxy?
Else it's likely that Tata might have started blocking torrent connections.
Yes. But that didn't help me..I had to go in for VPN otherwise the DHT list was about 20% of what it should have normally been. Simple unable to connect to the swarm. I face no issues with Airtel. Unless of course TPBB blocks torrents which I don't believe they do.
DHT is disabled in private torrents and you cannot enable it. This does not mean DHT is disabled globally.
The reason BitComet is banned among most private trackers is that it purposefully enabled it, which loses the purpose of having a thing.. yk.. private.
@gsd96974 is your city Bangalore? As I mentioned in my post on that thread you will need to contact the TPBB call centre. Whether they can provide a connection or not depends on the locality where you live or where you want the connection for e.g. in an office. Alternatively you can try buying a connection online. Fill up the form and they will get in touch with an update after doing a feasibility check.
